What is the optimal number of currencies in the world? Common currencies affect trading costs and, thereby, the amounts of trade, output, and consumption. From the perspective of monetary policy, the adoption of another country's currency trades off the benefits of commitment to price stability against the loss of an independent stabilization policy. The nature of the tradeoff depends on co-movements of disturbances, on distance, trading costs, and on institutional arrangements such as the willingness of anchor countries to accommodate to the interests of clients.
This paper evaluates the effects of fiscal policy on investment using a panel of OECD countries. We find a sizeable negative effect of public spending—and in particular of its wage component—on profits and on business investment. This result is consistent with different theoretical models in which government employment creates wage pressure for the private sector. Various types of taxes also have negative effects on profits, but, interestingly, the effects of government spending on investment are larger than those of taxes. Our results can explain the so-called “non-Keynesian” (i.e., expansionary) effects of fiscal adjustments.
Both individual experiences and community characteristics influence how much people trust each other. Using individual level data drawn from US localities we find that the strongest factors associated with low trust are: (i) a recent history of traumatic experiences; (ii) belonging to a group that historically felt discriminated against, such as minorities (blacks in particular) and, to a lesser extent, women; (iii) being economically unsuccessful in terms of income and education; (iv) living in a racially mixed community and/or in one with a high degree of income disparity. Religious beliefs and ethnic origins do not significantly affect trust. The role of racial cleavages leading to low trust is confirmed when we explicitly account for individual preferences on inter racial relationships: within the same community, individuals who express stronger feelings against racial integration trust relatively less the more racially heterogeneous the community is.
Critics of foreign aid programs argue that these funds often support corrupt governments and inefficient bureaucracies. Supporters argue that foreign aid can be used to reward good governments. This paper documents that there is no evidence that less corrupt governments receive more foreign aid. On the contrary, according to some measures of corruption, more corrupt governments receive more aid. Also, we could not find any evidence that an increase in foreign aid reduces corruption. In summary, the answer to the question posed in the title is 'no.'

As the number of independent countries increases and their economies become more integrated, we would expect to observe more multi-country currency unions. This paper explores the pros and cons for different countries to adopt as an anchor the dollar, the euro, or the yen. Although there appear to be reasonably well-defined euro and dollar areas, there does not seem to be a yen area. We also address the question of how trade and co-movements of outputs and prices would respond to the formation of a currency union. This response is important because the decision of a country to join a union would depend on how the union affects trade and co-movements.
This paper examines the regional distribution of public employment in Italy. It documents two facts. The first is that public employment is used as a subsidy from the North to the less wealthy South. About half of the wage bill in the South of Italy can be identified as a subsidy. Both the size of public employment and the level of wages are used as a redistributive device. The second fact concerns the effects of subsidized public employment on individuals’ attitudes toward job search, education, “risk taking” activities, and so on. Public employment discourages the development of market activities in the South.
In standard spatial models of elections, parties with policy preferences take divergent positions. Their platform positions are less separated than are the parties’ ideal policies. If policy is the result of an executive–legislative compromise, the policy preferences of the parties can be moderated by voter behavior. Divided government may result. Since parties anticipate the moderated outcomes, they have an added incentive to choose separated platforms. Consequently, divergence in platforms is greater than in the standard model, especially when uncertainty is high and the legislature more powerful than the executive. For some parameters, parties may even ‘posture’ by adopting platforms that are more extreme than their ‘true’ ideal points.
This paper studies the pattern of allocation of foreign aid from various donors to receiving countries. We find considerable evidence that the direction of foreign aid is dictated by political and strategic considerations, much more than by the economic needs and policy performance of the recipients. Colonial past and political alliances are the major determinants of foreign aid. At the margin, however, countries that democratize receive more aid, ceteris paribus. While foreign aid flows respond more to political variables, foreign direct investments are more sensitive to economic incentives, particularly property rights in the receiving countries. We also uncover significant differences in the behavior of different donors.
This paper studies what determines group formation and the degree of participation when the population is heterogeneous, both in terms of income and race or ethnicity. We are especially interested in whether and how much the degree of heterogeneity in communities influences the amount of participation in different types of groups. Using survey data on group membership and data on U. S. localities, we flnd that, after controlling for many individual characteristics, participation in social activities is significantly lower in more unequal and in more racially or ethnically fragmented localities. We also find that those individuals who express views against racial mixing are less prone to participate in groups the more racially heterogeneous their community is. These results are consistent with our model of group formation.
